Abstract (en)

[origin: US2003231176A1] To provide a drawing device with which drawing speed can be increased without escalation of price of it. A drawing device is established as a GPU on an entertainment device to perform the drawing to a frame buffer in terms of one of different interleaved patterns. Each interleaved pattern is specified by a combination of pixel segments in the frame buffer. The GPU identifies the shape of a figure to be drawn and selects the interleaved pattern that fits for the selected shape of the figure. The pixel segments specified in the frame buffer are not overlapped with other pixel segments in the same interleaved pattern regardless of which interleaved pattern is selected.
